Which lamp wattage has a higher paper amps value according to the data?

• A. 1000W lamp
• B. 5kW lamp
• C. Both have the same
• D. Cannot determine

Answer: (B)

The key idea is how current relates to power when the supply voltage is fixed. Current is equal to power divided by voltage (I = P / V). So, at the same voltage, increasing the wattage increases the current. That means a higher-wattage lamp will draw more current, which shows up as a higher paper amps value on the data sheet. For example, at a typical line voltage of 120 V, a lamp rated at 1000 W draws about 8.3 A, while a lamp rated at 5000 W draws about 41.7 A. At 240 V, those numbers would be about 4.2 A and 20.8 A, respectively. In both cases, the higher-wattage lamp has the larger current rating. So the lamp with greater wattage has the higher amps on its data sheet.
